@PennyChan,
The term "kinetic response" refers to a military response (i.e. physical violence such as bombing).
The word kinetic means "related to or involving motion". It's a silly military euphemism, like "collateral damage" (meaning civilian casualties) which seeks to sanitize and render abstract the horrors of war so as to make them, and the military and foreign policy behind them, more abstract and acceptable to the general population.
These euphemisms are not only silly, they are also poor English. They were "big words" invented by not very literate military types to try to sound impressive while obscuring what they really mean. Unfortunately, the news media (certainly cable television news) has accepted and adopted this language, instead of ridiculing it.
